Image of a 4-month-old girl with infantile hemangioma who had near complete regression after 1 year of propranolol treatment.
(a) Initial gray-scale US image shows a hypoechoic subcutaneous mass (arrows) without deep tissue involvement. Lesion length was defined as the longest diameter of the tumor (distance between arrows). Lesion height was defined as the longest distance between superficial and deep margins of the lesion (distance between arrowheads). (b) Initial color Doppler image depicts hypervascularity within the lesion (arrows). (c) Follow-up gray-scale US image shows decreased size of the lesion (arrows) (d) Follow-up color Doppler image depicts hypovascularity within the lesion (arrows), showing interval decreased vascularity.

Image from a 4-month-old girl with infantile hemangioma who showed incomplete regression after 1 year of propranolol treatment.
(a) Gray-scale US image shows a hyperechoic subcutaneous mass with a thick skin lesion (arrows). (b) Color Doppler image reveals hypo vascularity within the lesion (arrows). (c) Axial T1-weighted MRI of the face shows a lobulated mass (arrows) with multiple fatty septa. (d) Axial T1-weighted fat-suppressed contrast-enhanced MR image of the face reveals homogeneously strong enhancement (arrows).
